Functional Genetics Explained: How Your DNA Can Shape Diet, Exercise & Health
What if the best diet, exercise routine, and health strategy for you depended partly on your genes?
In this episode of The Curious Cardiologist, Dr. Sanjay Bhojraj sits down with Dr. Sam Shay, DC, IFMCP, functional medicine practitioner, genetics educator, and Western Hemisphere distributor for FitGenes, to explore how functional genetics can help us better understand individual health differences.
Dr. Shay explains why genetic predispositions don't have to determine our future—and how lifestyle, nutrition, and environmental factors can influence the way our genes are expressed.
Together, they explore:
- Functional genetics and epigenetics: Why genes are not necessarily destiny, and how environmental factors influence gene expression.
- Personalized nutrition: How genetic differences may influence responses to carbohydrates, fats, caffeine, gluten, histamine, and other dietary triggers.
- The seven drivers of chronic disease: Dr. Shay's framework for prioritizing inflammation, free radical management, liver detoxification, vitamin D receptors, methylation, cardiovascular health, and fat and energy metabolism.
- Exercise and recovery: Why genetics may influence exercise tolerance, inflammation, and recovery needs.
- The five categories of functional testing: Genetics, gut health, hormones, mitochondria and metabolism, and environmental exposures or other infections.
- Genetic testing methods: Why Dr. Shay emphasizes looking beyond basic genetic variations to include copy number analysis.
- A broader definition of health: The difference between having no symptoms and actively working toward better health.
The conversation also explores the importance of humor in healthcare, Dr. Shay's personal connection to cardiovascular disease, and the value of bringing conventional and functional medicine perspectives together.
